In contrast, the INS form of the polymorphism acted as a repressor
, and a pharmacologic increase in cAMP did not result in increased gene transcription.
The bisin gene cluster is supposed to involve lantibiotic lanADMIT genes for production and immunity, with lanR2K encoding the two-component signal transduction regulatory system and lanR1 encoding a putative repressor
. To substantiate this, and to enable large-scale production of bisin, scientists at the University of Minnesota engineered Lactococcus lactis to express the production and immunity genes.
We found four viable primer sets corresponding to partial sequences of the dUTPase gene (x2), a repressor
gene and a hypothetical gene with unknown function.
Mounting data support that metabolic substrate selection drives inflammation in innate and adaptive immune cell effector and repressor
Mathematical analysis of the kinetics of the lac repressor
operator interaction in the E.
He writes: "It was in the Communist bookshop on calle Carlos III in Havana that future commander and repressor
Fidel Castro bought the two key books in his life: The Communist Manifesto and The State and Revolution" While the bookshops on calle Obispo remain (La Moderna Poesia, which dates to the nineteenth century, comes to mind), they have been reduced to little more than tourist spots whose sparsely stocked shelves sell official histories of the revolution and biographies of Che and Fidel.
Colonies were selected with clear zones of dissolved xylan in toxic 2-DG presence as catabolite repressor
on agar screening plates containing Rose Bengal.
As mentioned before, the network also contains experimentally obtained weighted values ([S.sub.i,j]) of the interactions between any pair of genes which indicates whether the effect of a gene over any other connected to it is positive (activator) or negative (repressor
), that is, there are transcription factors whose "preferential" activity is either of an activating or repressing nature.
We demonstrate that SCO1678 encodes a repressor
of the gluconate operon and that the promoter of gluconate kinase gene SCO1679 is the main target of Sco1678 regulatory action.
Zinc finger protein 132 (ZNF132) is a transcriptional repressor
and plays an important role in animal production traits.
A recombinase gene encodes a protein with recombinase activity, which cleaves the blocking sequence linked to the toxic gene by means of a repressor
compound produced by a third gene.
